A really simple currency converter using XavierMedia API. Compatible with Ruby 1.8, 1.9, JRuby 1.5.3 and Rubinius 1.1.
Since version 1.2, simple_currency no longer uses Xurrency API in its background, due to restrictions on the number of daily requests. If you would like to use it, please use the fork by Alfonso Jiménez, author and maintainer of xurrency.com service.
Just require it and all your numeric stuff gets this fancy DSL for free:
30.eur.to_usd
# => 38.08
150.eur.to_usd
# => 190.4
239.usd.to_eur
# => 187.98
# These don't even hit the Internets!
# (They take advantage of Rails cache)
70.usd.to_chf
# => 71.9
But what if you want to do the currency exchange according to a specific date in the past? Just do this:
# You can use any time or date object
42.eur.at(1.year.ago).to_usd
# => 60.12
42.eur.at(Time.parse('2009-09-01')).to_usd
# => 60.12
You can also add an subtract money expressions, which will return a result converted to the former currency of the expression:
42.eur + 30.usd
# => The same as adding 42 and 30.usd.to_eur
10.gbp + 1.eur
# => The same as adding 10 and 1.eur.to_gbp
In your Gemfile:
gem "simple_currency"
Then you have to manually install the gem:
gem install simple_currency
And manually require it as well:
require "simple_currency"
